Won't start when hot.

I have a rockwell with the Walbro carb on it. When cold with choke on and three primes starts right up first pull. Once hot if it sits a few minutes, it will not start, I have to wait until it cools downs again. I'm thinking bad seals?

usually bad seals will make one cylinder cut in and out, especially at low rpms. Run the motor till it's at normal operating temp, and wait a few minutes, verify that it won't start and then check for spark. Sometimes when the ignition coils get old, they fail when they get heat soak, Give it a try and let us know what you find.

Will do thanks! Of course all the snow here in Ohio melted today. It may be awhile before I get to try that.
